The Plot Thickens (1936)
Oscar Piper: [Parodying the witnesses reactions out of frustration] "I don't know," "You don't know," It's funny. Nobody seems to know nothing! around here!
Hildegarde Withers: Hah! I wouldn't broadcast that if I were you, Oscar.
Oscar Piper: [Frustrated when it seems Cassidy can't remember anything] You'll go a long ways... a long ways out in the sticks.
Cassidy - Policeman: Thank you, sir.
Oscar Piper: [Seeing a piece of evidence] I saw this on Carter's desk this morning.
Hildegarde Withers: Sure, and it went in one eye and out the other.
Hildegarde Withers: Now don't behave more stupid than is natural, Oscar.
Kendall: Oh, it was horrible, sir. Why, I thought...
Oscar Piper: [Interrupting impatiently] Never mind what you thought. What'd you do?
Hildegarde Withers: Inspector, I have a feeling there's more to this case than meets the eye.
Oscar Piper: You say that about every case.
